UFC legend B.J. Penn added to UFC 199 card on June 4 at Forum

Former two-division Ultimate Fighting Championship champion B.J. Penn will return from retirement and fight veteran Dennis Siver (22-11) at the Forum at UFC 199 on June 4.

Hawaii’s Penn (16-10-2) has taken a two-year hiatus since a 2014 loss to former lightweight champion Frankie Edgar in a featherweight bout.

Penn, considered one of the best fighters in mixed martial arts history, joins UFC Hall of Fame inductee Randy Couture as one of two men to hold a UFC championship in two weight classes. Penn is a former lightweight and welterweight champion.

He has trained for his comeback at Jackson-Wink MMA in Albuquerque, the gym which boasts former light-heavyweight champion Jon Jones, former women’s bantamweight champion Holly Holm and recent welterweight title challenger Carlos Condit.

Penn’s return was delayed in February after allegations surfaced from a former employee who accused Penn of sexually assaulting his girlfriend. Penn denied all allegations.

The UFC issued a statement Wednesday that stated a third-party investigation by a UFC-employed Las Vegas-based law firm showed no criminal or civil charges have been filed against Penn, adding no action has been taken by law enforcement.

The UFC reserved the right to reevaluate the matter if new information becomes available.

Penn was inducted into the UFC Hall of Fame in 2015 and has the all-time lightweight title defense record, but was winless in his last four UFC bouts. His most recent victory was in 2010 against former welterweight champion Matt Hughes.

Penn was once one of the more popular fighters in the UFC, with high-profile bouts against Georges St-Pierre, Matt Serra, Nick Diaz, Hughes, Edgar and Rory McDonald.

A middleweight championship rematch between Luke Rockhold (15-2) and former champion Chris Weidman (13-1) will be the main event at UFC 199.
